Rice University scientists have found significant differences between the methods signaling pathways use to prompt cells to differentiate – that is, whether to become organs, bone, blood vessels, nerves or skin.

DNA replication is a complex process in which a helicase ring separates the DNA molecule's two entwined and encoded strands, allowing each to precisely reproduce its missing half. Until recently, however, researchers have ...

Food, microbes, and medicine all clump together as they move through our gut. Sticky molecules secreted into our intestines bind the gut particles in the same way that flour holds a ball of dough together. Now a new mice-based ...

CRISPR/Cas enables the targeted deactivation of genes by cutting DNA at pre-determined sites. This is accomplished by providing the Cas enzyme with a genetic zip code. Using an entire library of zip codes, it is then possible ...

The TMEM16 family of membrane proteins was hailed as representing the elusive calcium-activated chloride channels. However, the majority of the family members turned out to be scramblases, proteins that shuffle lipids between ...
